Abstract: At present, the major problems of second-season rice mechanized seedling cultivate and transplant is: The growth period of species which has been used was too long and the age of seedling exceeds the right moment. The out seedling was not tidy and the rate of out seedling was low. The high of seedling was over the proper degree. To select the species which have the proper growing period, irrigate at day and drain during night after sowing, reduce the use of fertilizer quantity, using Paclobutrazol to control the high of seedling can resolve above problems. Expansion of the technique of mechanized rice seedling transplant will be helpful to reduce the cost and increase output and income.
